/* ============================================================
   Sales Assistants — Shared Design Tokens  (SINGLE SOURCE OF TRUTH)
   ------------------------------------------------------------
   Loaded by EVERY frontend surface (Mini App dashboard, templates,
   future panels) so they all "speak the same language".

   Two-sided compatibility on purpose:
     - --color-*  : the public/light-first token set used by style.css
                    and workflow/template pages (Telegram theme-aware).
     - --accent/--card-bg/--text-* : the dark-first set the Mini App
                    dashboard uses today. Kept as ALIASES of the color-*
                    tokens so both vocabularies resolve to one value.

   RULE: never redefine a raw color in a page <style> block. Pull a token.
